An arteriogram is a test that allows a doctor to see the arteries on an
x-ray
. A contrast dye is injected into the arteries to make them visible. The test makes images that can be used to diagnose and treat problems in the arteries.

Reasons for Test

An arteriogram is done to check the arteries for narrowing, bulging, or blockages. These could be signs of disease.

Talk to your doctor if you take any medications, herbs, or supplements.

You may need to stop taking some medications up to one week before the procedure, like:

Aspirin and other nonsteroidal anti-inflammatory drugs, such as ibuprofen or naproxen

Blood thinners, such as warfarin

Anti-platelets, such as clopidogrel

Do not eat or drink anything after midnight the night before your procedure.

Anesthesia

You will have an IV placed in your arm to give you medications. These medications will make you feel sleepy and comfortable.

Description of the Procedure

For this procedure, you will have a catheter placed in your groin or elbow so that the doctor can inject the contrast dye. The skin where the catheter will be placed will be cleaned. The doctor will make a tiny cut. The doctor will then insert a hollow needle into the artery. A thin wire will be placed into the artery. The catheter will be threaded over the wire, and the wire will be removed.

The doctor will use the catheter to inject a contrast dye into your artery. The dye may cause you to feel warm or flushed for a few moments. The doctor will take x-rays to see how the contrast dye is moving through your arteries. You will need to lie still to prevent blurry images.

How Long Will It Take?

About one hour.

Will It Hurt?

Although the procedure is not painful, you may feel:

A brief sting when local anesthesia is injected

Pressure when catheter is inserted

Hot and flushed when contrast dye is injected

Post-procedure Care

After the test, the catheter will be removed. The IV will also be removed from your arm.

At the Care Center

Immediately following the procedure:

You will need to be monitored for about six hours.

The doctor or a nurse may press on the insertion site for 10-20 minutes to stop the bleeding.

You will need to keep the arm or leg where the catheter was inserted straight. This will minimize bleeding.

You will be encouraged to drink a lot of fluids to flush the contrast material from your system.

At Home

When you return home, take these steps:

Follow your doctor’s instructions on cleaning the incision site.

Ask your doctor about when it is safe to shower, bathe, or soak in water.

You may eat normally. Continue to drink plenty of fluids for 1-2 days.
